"FontStruct is a free font-building tool brought to you by the world's leading retailer of digital type, FontShop.
FontStruct lets you quickly and easily create fonts constructed out of geometrical shapes, which are arranged in a grid pattern, like tiles or bricks.
You create 'FontStructions' using the 'FontStructor' font editor.
Once you're done building, FontStruct generates high-quality TrueType fonts, ready to use in any Mac or Windows application.
You can keep your creations to yourself, but we encourage users to share their "FontStructions". Explore the Gallery of fonts made by other FontStruct users and download them or even copy them and make your own variations.
You can also use the FontStruct widget to show your FontStructions on your own website or blog."
